Question: Design a digital FIR lowpass filter (with the following specifications): wo = 0.21, R, = 0.25 dB, w, = 0.31, A, - 50 dB Choose an appropriate window function from Table 7.1 of book "Digital signal processing using MATLAB" 3rd edition by Vinay K. Ingle and John G. Proakis. (0) Plot the impulse response and provide a plot of the frequency response of the designed filter (ii) Chose an input signal of your choice (plot it as well) and show filtered signal. Do this for both: first by adjusting frequency of input signal within pass band and then adjusting it into stop band (iii) show all the steps "how to perform part (ii)" using code composer studio
